I find this way specially fast as no actual data should be copied in the
process:

naarr = numarray.array(buffer(arr), type=arr.typecode(), shape=arr.shape)

that works for any Numeric object (except for typecode 'c').

And for the reverse case, this should work just fine:

arr=Numeric.array(naarr.tolist(), typecode=naarr.typecode())

although in this case, a data buffer copy is actually made.

Hope that helps,
